Meccha Chameleon, launched on June 9, has sold over 10 million copies within three weeks, developed by two Japanese indie developers, Lemorion and Haganeiro, in a rapid two-month timeline. The developers utilized a strategy of creating a basic mockup and reusing assets from previous projects to streamline their process. The game has received significant sales, particularly in Western markets, with 20,712 English reviews out of 36,810 on Steam. This success has likely allowed the developers to benefit from a reduced revenue cut from Valve, earning them potentially "life-changing" income. If sales continue at the current pace, they could retroactively claim a day rate of approximately million for their work. Meccha Chameleon has also been well-received for its engaging gameplay, earning a score of 82%.
